Question

Hallo How to ? 1. find intersection two line in 3D (with XYZ coord) ? know Point A (Xa Ya Za) and point B (XbYbZb) 2. find intersection line and spher 3D ? know Point A (Xa Ya Za) and center sphere point B (XbYbZb) with radius 3. find intersection between two sphers ? know center spherePoint A (Xa Ya Za) and center sphere point B (XbYbZb) with radius 4. find intersection between three spheres ? i need code algorythm manual links Thanks
